Bi-directional synchronous loading hydroforming equipment for sealing ring of aero-engine

Abstract

The invention discloses a two-way synchronous loading hydraulic forming equipment for sealing rings of aero-engines, which includes an automatic mold loading system, a host system, an ultra-high pressure system and a numerical control system; hydraulic cylinder and a clamping hydraulic cylinder. In addition to driving the hydraulic cylinder, the ultra-high pressure system also provides a maximum bulging pressure of 100MPa, which can be dynamically adjusted with the feed displacement of the servo hydraulic cylinder to meet the requirements of two-way synchronous loading hydroforming of special-shaped cross-section members such as high-temperature alloys. The numerical control system is based on the control mode of upper and lower computers, and has intelligent functions such as database and parameter analysis. The present invention adopts closed-loop control, integrates functions such as accurate load application, servo drive / hydraulic constant load compound control, load / pressure real-time detection, and intelligent compensation of forming errors, etc., realizing the integration and automation of bidirectional loading bulging process and ensuring product quality consistency and stability.

Description

technical field [0001] The invention belongs to the field of hydraulic forming, and relates to a bidirectional synchronous loading of an aeroengine sealing ring that integrates precise load application, servo drive / hydraulic constant load composite control, load / pressure real-time detection, intelligent compensation of forming errors, and automatic mold loading. Hydroforming equipment. Background technique [0002] Metal sealing ring is a kind of axial self-tightening static sealing structure with new sealing form and better sealing effect. The cross section is generally "W", "M" or more complex multi-corrugated shape. The metal sealing ring has the advantages of good resilience, strong vibration absorption, large deformation range and long life. It is a key basic part for sealing leakage in high temperature, high pressure, vibration and strong corrosion environments in aero-engines. [0003] Hydroforming is a plastic processing technology that uses liquid as a force transm...
